STEAM COOKING APPARATUS.

Specification of Letters Patent.

Patented March 12, 1907.

` Application filed March 26,1906. Serial No. 308,096.

.To a/ZZ whom. 1f/'may concern? I Be it known that I, WLLIAM C. SALMON,

a citizen of the United States, residing at Minneapolis, in the county of Hennepin and -State of Minnesota, have invented new and useful Improvements in Steam Cooking Apparatus, of which'the following is a specification. This invention relates to a steam cooking apparatus, and consists in the construction and arrangement of the several parts, which will be more fully hereinafter set forth.

The object of the invention is to provide a simple and effective steam cooking apparatus that may be readily cleaned and wherein also the several joints of the connected parts yare rendered tightto prevent theescape of' steam, and thus reduce the amount of-'heat for carrying on the cooking operation in the several compartments and also materially expeditesuch cooking operation.

In the drawin Iligurel .is`a transverse vertical section o' a steam cooking apparatus embodying the features of the invention. Fig. 2 is a detail elevation of one of the com partments.

Similar numerals of reference are employed to indicate liker parts in the several veiws. l

The numeral 1 designates a steam-generating water chamber or boiler of suitable dimensions, which is open at the to and has aninlet-aperture 2 at the side, wit a guard 3 projecting above the same and serving as means for replenishing the boiler with water,y

if found necessary.

Coperating with the boiler 1 are a series of compartments or receptacles 4, 5, 6, and 7, each of which is practically similar in construction to the others of the group, with the exception of the compartment or receptacle 4, which has therein a bottom drip-chamber 8, with a erforated top 9 and a meat-rece tacle 10, t e top 9 serving as a bottom for t e said latter receptacle. The drip-chamber 8 has an outlet or draw-off `cock 11, and over the inner end thereof communicating with said'drip-chamber is a suitable strainer 12. The bottom 13 of the drip-chamber is imperforate and is located closely over the upper rim or edge of the boiler 1 when the parts of the apparatus are assembled. The side Wall of t e ldrip-chamber 8 may be also perforated, as at 14, Vto permit a'portion of the drip ings to pass directly from the receptacle-c amber into the chamber 8, and communicating with the meat-receptacle 10 is a drip-duct 15, having an upper open end in which a drip-tube 16, forming part of the structure of the compartment or receptacle 5 next above, extends. Each of the receptacles 5, 6, and 7 is provided with a drip-tube 16, and the lower end of one drip-tube separably fits in the upper'end of the adjacentdrip-tube, thus forming a continuous driptube throughout the series of compartments or receptacles 5, 6, and 7. The upper end of the drip-tube' 16 in the compartment 7 is fully open, and at suitable elevations in the compartments or receptacles 5 and 6 the drip-tubes 16 are formed with apertures 17, so that the vapors rising to the top portions of the several compartments may flow down-y wardly through the drip-tubes into the dripduct 15, if desired, and eventually passb into the drip-chamber 8. Each drip-tube, however, has a cut-off valve' 18 therein, which is operated by an'outwardly-projecting valve stem or rod 19, each of the' stems or'rods 19 -being extremely accessible and operativev to prevent the vaporsfrom any receptacle or `from two' or more of the receptacles from escaping into and passing downwardly through 'the connected drip-tubes 16.

The several compartments or receptacles 4, 5, 6, and 7 are supplied with steam from the boiler 1 by a vertical steam-pipe formed in sections 20 carried by each compartment or receptacle and made to communicate with the latter by an angularl coupling branch or pipe 21, communicatingwith the up er 'portion of each receptacle, as shown. T e lowerend of the steam-pipe section 20, carried by the compartment or receptacle 4, is removably fltted in the upper end of an elbow 22, connected to and communicating with the upper portion of the boiler 1. end of the section 20 of the uppermost coin- 4artrn'ent or rece tacle 7 a cap or cover is oosely fitted. T e joints of the pi e-sections 20 are covered by movable thimb es 20a to form joints. g

The upper edge of the boiler 1 and of each compartment or receptacle is formed with a substantially V-shaped seat 23, in which is f On the upper ICO depending inwardly-inclined flange 25 to closely engage the seat therefor in the up er vedge of the compartment or boiler in Whic it res'ts, leaving sucient space, as at 26,. to

`several compartments and the boiler.

v bottoms 27 of the'several compartments are imperforate at the points where the drip-tubes pass therethrough. At the joints of the steampipe sections 20 the same structure may be provided as at the joints of the several receptacles, and in addition thimbles or sleeves 20a will be slipped over the said joints to doubly insure the tightness of connection of the several steam-pipe sections and obviate leakage.

The uppermost compartment or receptacle 7 has a lid or cover 29 removably applied thereto and provided with an inwardlyinclined llange 30, which forms a tight joint with the seat 23 at the upper edge of the said compartment or receptacle. Furthermore, each compartment or receptacle will be provided with hand-grips 31- at diametrieally opposite points to facilitate application and withdrawal thereof.

Any number oi' the receptacles shown may be used with the boiler, and from the foregoing description the operation of cooking Will be readily appreciated. The meat is placed in the receptacle 10 and vegetables disposed .in the compartments or receptacles 5, 6, and 7. As the water boils in the boiler 1 the steam will pass upwardly and enter the upper portions of the several compartments, and

the condensed vapors from the vegetables, if

desired, will pass down into the drip-chamber S. The meat-drippings will pass through the perforated top 9 o1 the chamber into the latter, and the vapors from the vegetables will mix or commingle with the meat-drippings, and thus produce av liquid which can\be served as soup and drawn oli as may be desired through the cock 11.

What I claim is y A steam cooking apparatus comprising a lower boiler with a seat at the top thereof partment next to the boiler having a meatreceptacle formed therein above the closed bottom thereof, the bottom ofthe meat-receptacle being perforated andforming with the bottom of the said lower compartment, a receptacle for meat-juices, a cock connected to the said lower receptacle and located on the exterior o'l' the lower compartment, a drip-duct at the upper portion of the lower compartment, a plurality of tubes carried by the compartments above the lower compartment and adapted to be joined when the compartments are assembled, the said tubes having cut-o'flisin each compartment and also openings communicating with the upper ortions o f the compartments, and a vertica steampipe formed. in sections carried by each compartment and communicating with the boiler. In testimony whereof I all'ix my signature in presence o'ftwo Witnesses.`.
